Code: LAUNCH for 40% off. Includes Butt Building Diet Guide, Women’s Supplement Guide, at-home dumbbell version and a free second program at checkout (Muscle Mommy or Muscle Mommy 15).
In this episode the guys break down the low reps vs. high reps debate — covering why both build muscle equally when intensity is matched, why low reps build maximal strength better and high reps build strength endurance, why low reps are easier to recover from, and why doing both in phases produces the best long term results. They also get into Sal starting SS-31 peptide and why he is noticing similar energy and clarity benefits to MOTS-C, Adam microdosing GLP-1 for psoriasis and inflammation and the emerging studies on autoimmune and addiction applications, a new pill that reduces sleep apnea breathing events by 44% by targeting neuromuscular dysfunction, the history and bizarre fashion resurgence of the merkin, a study showing HEPA air filters improved executive function by 12% in 30 days, otter attacks being more serious than anyone expected, Adam’s daughter calling her bikini top a boob mask, Manukora as part of the anti-viral immunity stack, a nationwide homeschool study showing 25-29 percentile point improvements across all subjects, and pickleball hitting 479% growth. Then they coach live callers submitted through mplivecaller.com.
